It is interesting that the debate here mirrors the scientific debate I have been reading for years on the Internet. What seems to be happening in reality is uncertain. The evidence can be read in multiple ways: warmer, colder or no change.
What is clear is that the models have not predicted what is actually happening, indicating that they have not fully accounted for all of the factors. Further and continued research is required.
Also, both sides of the debate should tone it down just a bit.
I personally believe that in the short term, humans can moderately increase the temperatures on earth. But whatever we do is dwarfed by long term natural phenomena, such as sunspot activity, orbital eccentricities or something deus ex machina like a comet's tail we every now and then pass through. (There is an article on this I read some years ago.) Prudence dictates that we make choices to reduce greenhouse gasses assuming the models are correct.
However, think about this: We are at the end of the longest interglacial period in the last million years. We should be heading into another ice age. Perhaps CO2 emissions are holding it off. Do we know whether the any of the models have orbital eccentricities in their calculations?
